Aerial footage shows the ruins of the Francis Scott Key Bridge after it was struck early this morning by the container ship Dali.

The 984-foot-long, Singapore-flagged ship reportedly lost control moments before it crashed into a bridge pillar.

The impact fractured the main truss span, which buckled and collapsed into the harbor, bringing down within seconds the two side spans.

The front end of the ship is currently pinned under the bridge’s wreckage.

According to Maryland Governor Wes Moore, ship personnel issued a Mayday call, notifying authorities they had lost power, shortly before the accident.

Moore also said officials were searching for six road repair workers who had been filling potholes on the bridge at the time of the crash.

Moore lauded the Maryland Transportation Authority (MDTA) police who stopped cars from continuing onto the bridge, thereby saving lives.

“These people are heroes,” Moore said.

Dali’s Reported Deficiencies

Officials had little to say at this early stage about problems with the bridge or with the ship or its crew that may have led to the crash.

Moore told reporters that the bridge was fully up to code and that this didn’t appear to be a structural problem.

As for the Dali, however, an inspection of the vessel last year in Chile reported that the vessel had a deficiency “related to propulsion and auxiliary machinery,” according to the New York Times.

The inspection specified that the deficiency concerned gauges and thermometers, the Times said.

In 2016, the ship collided with its berth at the Port of Antwerp, causing significant damage to the ship and the berth, according to vesselfinder.com.

The incident occurred “in good weather and was caused by mistake of the master and pilot on board,” according to the website.
